5.5. Installing New Software

You should use the yum install command to install the latest version of a package or package group and at the same time ensuring that all dependencies are satisfied in the process.

You must specify the desired package names, if it does not succeed with the specified names, it will assume that these names are "shell glob " and any matching obtained from the repositories will be installed.

If it fails to identify the package, then a search will be performed.

5.5.1. Install from the enabled repositories

In the previous example we want to install xfig but a number of uninstalled dependencies are needed.

yum has detected this and it has included the dependencies needed to succeed in the task.
